Here is a sample installation on a node hosting 4 HDDs and 1 SSD. In a
typical deployment, you set up one rawx service per HDD (plus its side services),
1 high-level directory service of each kind (account, meta0, meta1) on the first
SSD, then 4 meta2 services per SSD. All the local stateless services are deployed
once, also on the first SSD.

Each service generates an execution journal as well as an access log. The
output is sent through the /dev/log device to the local systemd-journald
service (we recommend also using rsyslogd as a backup). The default
configuration organizes log files per service in the /var/log/oio/sds/{NAMESPACE}
directory.

The configuration of a service resides in the /etc/oio/sds/{NAMESPACE}
directory. At that path, in addition to one directory used to host occasional
core dumps, each partition used by an OIO SDS service is stored.
